Step-by-step explanation:

Step 1: Flip the equation.

−5x−2=11

Step 2: Add 2 to both sides.

−5x−2+2=11+2

−5x=13

Step 3: Divide both sides by -5.

-5x     13

----- = -----

-5        -5

x = -13/5

Answer:

350

Step-by-step explanation:

350 because there are 1/12 of VIP seats and there are 600 so 600 times 1/12 is 6,600.

Then you minus off the 600 VIP seats so you get 6000

next you do 600 divided bu 12 because of the 1st tier seats and 2nd tier seats combined which then you get 50

lastly you do 50 times 7 because of the ration 7:5 1st tier seats to 2nd tier seats so then you get 350

Speed is the ratio of distance and time

The elapsed time is the difference between the final time and the initial time.

So, we have:

Time elapsed = 4.5 seconds - 1.5 seconds

Evaluate the difference

Time elapsed = 3 seconds

Hence, the elapsed time is 3 s

The average speed is the quotient of the distance and the elapsed time.

So, we have:

Average speed = 4 meters/ 3 seconds

Evaluate the quotient

Average speed = 1.33 meters per second

Hence, the average speed is 1.33 m/s

The distance from point A to B is 2723.8 feet.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let h represent the height of the light house, hence:

tan(9) = h/1347

h = 213.3 feet

Let d represent the distance from point B to the lighthouse base, hence:

tan(3) = 213.3/d

d = 4070.8 feet

Distance from point A to B = 4070.8 feet - 1347= 2723.8 feet.

Answer:

$94.325

Step-by-step explanation:

Given interest (I) varies directly as rate of interest (R) then the equation relating them is

I = kR ← k is the constant of variation

To find k use the condition I = 49 when R = 4 , then

49 = 4k ( divide both sides by 4 )

12.25 = k

I = 12.25R ← equation of variation

When R = 7.7 , then

I = 12.25 × 7.7 = $94.325

[tex]x^{2} -5x-14\\\\x^{2} -7x+2x-14\\\\x(x-7)+2(x-7)\\\\\(x+2)(x-7)[/tex]

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 3.875/100

r = 0.03875 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 10,000.00(1 + 0.03875/12)(12)(7.5)

A = 10,000.00(1 + 0.003229167)(90)

A = $13,366.37

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $10,000.00 at a rate of 3.875% per year compounded 12 times per year over 7.5 years is $13,366.37.

Renal can buy a box that is $35

Step-by-step explanation:

The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Renaldo has a budget of $500 to buy gift boxes for a party. Large boxes cost $65 and small boxes cost $35.

Let 'x' be the number of small boxes and 'y' be the number of large boxes. Then the inequality is written as,

35x + 65y ≤ 500

If Renaldo buys 5 small gift boxes. Then the number of large gift boxes will be given as,

35 × 5 + 65y ≤ 500

175 + 65y ≤ 500

65y ≤ 325

y ≤ 5

The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.

Standard form:   y = 2x² - 8x + 1

Step-by-step explanation:

We are given the following quadratic function, y = 2(x - 2)² - 7, for which we must transform in its standard form.

The vertex form of a quadratic function is y = a(x - h)² + k (which is the format of the given equation).

⇒  If the value of "a" is positive, then the vertex is its minimum or lowest point on the graph.

⇒  If the value of "a" is negative, then the vertex is the maximum or highest point  on the graph.

The standard form of a quadratic function is y = ax² + bx + c, where a ≠ 0.

The first step in rewriting the given equation into its standard form  is expanding the binomial using the FOIL method, which transforms it into a perfect square trinomial.  

y = 2(x - 2)² - 7

       ⇒   (x - 2)(x - 2)

       ⇒   [ x² - 2x - 2x + 4 ]

y = 2(x - 2)² - 7

y = 2(x² - 2x - 2x + 4) - 7

y = 2(x² - 2x - 2x + 4) - 7

y = 2x² - 4x - 4x + 8 - 7

y = 2x² - 8x + 1.

Therefore, the quadratic function in standard form is y = 2x² - 8x + 1, where a = 2, b = -8, and c = 1.

Answer:

9 units²

Step-by-step explanation:

**Refer to the attached diagram**

The angles in the right triangle FAD (and HBE) are 30-60-90 which means that its sides will be in the ratio 1 : √3 : 2

Let x = the smallest side

Therefore, the sides of the right triangle FAD are in the ratio  x : √3x : 2x

This means that:

We are told that the side length of the triangle is 3 + 2√3, so:

[tex]\implies 3 + 2\sqrt{3} =(2 + \sqrt{3} )x[/tex]

[tex]\implies x=\dfrac{3 + 2\sqrt{3}}{2 + \sqrt{3} }[/tex]

[tex]\implies x=\sqrt{3}[/tex]

As the side length of the square is √3x,  and x = √3,

⇒ side length of the square = √3 x √3 = 3

Now we know the side length of the square, we can calculate the area:

⇒ area of a square = side length x side length = 3 x 3 = 9 units²
